Abstract
Nella testa in oggetto è prevista, realizzata al suo interno ed in corrispondenza del fondo della sede (6) di alloggiamento di una turbina, una sede toroidale (8) collegantesi, in corrispondenza del proprio fondo, con un condotto di alimentazione (4); entro questa sede toroidale (8) è alloggiato un primo anello (9) presentante una cavità (10) di collegamento con un altro condotto di alimentazione (5) mediante un foro laterale (11) e presentante la propria porzione non interessata dalla cavità (10) con una configurazione tale da sposare parzialmente la sede toroidale (8) così da definire, inferiormente, un meato (12) di passaggio per il fluido proveniente dal primo dei condotti di alimentazione (4); il primo anello (9) è previsto di una serie di fori (13) passanti di collegamento della cavità (10) con il meato (12) e con una corrispondente serie di secondi condotti (7a) inclinati di uscita, realizzati sulla porzione inferiore della testa (2), così da permettere l'uscita di un flusso di detta aria ed acqua convergente nell'intorno dell'estremità operativa di un utensile (3); un secondo anello (15) è previsto inseribile sull'estremità aperta della sede toroidale (8) atto a permettere la chiusura a tenuta della stessa sede (8) e della cavità (10) del primo anello (9). (FIG. 2)In the head in question, a toroidal seat (8) is provided inside and in correspondence with the bottom of the seat (6) for housing a turbine, connecting, in correspondence with its bottom, with a supply conduit (4); inside this toroidal seat (8) there is housed a first ring (9) having a cavity (10) for connection with another supply conduit (5) by means of a lateral hole (11) and having its own portion not affected by the cavity (10 ) with a configuration that partially marries the toroidal seat (8) so as to define, at the bottom, a meatus (12) for the passage of the fluid coming from the first of the supply pipes (4); the first ring (9) is provided with a series of through holes (13) for connecting the cavity (10) with the meatus (12) and with a corresponding series of second inclined outlet conduits (7a), made on the lower portion of the head (2), so as to allow the exit of a flow of said air and water converging around the operative end of a tool (3); a second ring (15) is provided which can be inserted on the open end of the toroidal seat (8) suitable for sealing the seat (8) and the cavity (10) of the first ring (9). (FIG. 2)
